It typically only takes 6 minutes of continuous pressure in the same position to cause lasting changes to the structure of your spine and its soft tissues (ligaments, discs).
Are you even aware of the amount of time you spend on your devices? Do you consciously position yourself for optimal posture while using them?
For most people, the answer is no. This is why "text/tech neck" has become such a prevalent issue causing everyone from young kids to seniors to experience neck pain, headaches/migraines, carpal tunnel syndrome, sleep apnea, and even numbness and tingling in their upper body.
Take action! Remember to keep your devices at, or slightly above, your eye level directly in front of you so that you are less likely to slouch or otherwise put yourself into a stressful, damaging posture. Time can be on your side if you know what you are doing.
